Abstract:

Black cotton soil is highly sensitive to the seasonal variation which causes distress to the structures that are built over it. Civil engineering infrastructures especially pavement suffer from premature failure. Stabilizing black cotton soil with chemical, cement, industrial waste, geotextiles, fibers etc have found to be effective in improving the strength of the black cotton soil. In the present study an attempt is made to study the effect of sisal fiber and cement with black cotton soil. In present work, experiment were conducted by replacing black cotton soil with the various percentage of sisal fiber from 0.2 to 1.2% by keeping the 5% of cement as constant, Compaction and Strength chatericties tests are Made. Due to the addition of sisal fibers to the soil there is a predominant increase in the strength of soil. It is observed that the UCS value of normal soil has been increased from 73.81 KN/m2 to 148.81 KN/m2to for zero day condition. Similarly, the UCS value is increased even in the case of soaking condition for 7 days and 14 days from 186.79 KN/m^2 to 273.39 KN/m^2 respectively. Overall, it can be concluded that fiber reinforced soil can be considered to be good ground improvement technique specially in engineering projects on weak, expansive soils.
